摘　　要：文中针对大容量柔性直流输电系统接入系统后大连电网的稳定性进行了较为细致的研究。首先在电磁暂态仿真软件PSCAD/EMTDC上搭建了大容量柔性直流输电系统的仿真模型以及实际的大连电网模型,研究大连电网在典型故障下的稳定性;其次研究柔性直流向无源网络供电的控制策略;最后研究了柔性直流频率/交流电压的附加控制策略,仿真结果表明,大容量柔性直流输电系统可以很好地提高大连电网的稳定性。In this paper, the stability analysis of Dalian grid connected by the high capacity flexible HVDC is researched.Firstly, the flexible HVDC simulation model and actual Dalian grid is built in the PSCAD/EMTDC software. Secondly, the control strategy supplying to passive network is researched. Finally, the frequency/AC voltage additional control strategy of the flexible HVDC is studied. The simulation results show that the flexible HVDC can improve stability of Dalian grid.
